Thermooxidative stability of crosslinked polypropylene

Thermooxidative stability of crosslinked polypropylene

Thermooxidative stability of crosslinked polypropylene was investigated. Surprisingly high stability was observed when polypropylene was crosslinked with peroxide in the presence of coagents p-benzoquinone or hydroquinone. It is suggested that binding of the coagent into a polymer network prevents t...

description Thermooxidative stability of crosslinked polypropylene was investigated. Surprisingly high stability was observed when polypropylene was crosslinked with peroxide in the presence of coagents p-benzoquinone or hydroquinone. It is suggested that binding of the coagent into a polymer network prevents the outlet of the quinone from the polymer at oxidation temperature. This is the main reason for the increase of thermooxidative stability due to crosslinking.
